When you open the game with a touchdown off a pick-6; when you take a 14-0 lead in the first five minutes of the game; when you later recover a muffed punt at around the opponent’s 10-yard-line and convert the turnover into a touchdown; when you take a 31-17 lead in the fourth quarter: you are supposed to win the game.
I thought the Browns coaching staff coaching staff did a nice job, down 14-0, of focusing on their game plan. It would have been very easy to panic in that situation and start throwing all over the yard.
